Material Availabilty Date Determination in Sales Order

Hi Gurus,

When creating the sales order, if stock is not available then how the material availability date is determined.

What are the inputs the system consider for calculating the material availability date.

Even though I am giving the total replenishment leadtime, Inhouse processing time(Lot size independent), GR processing time and even the planned delivery time, the system proposing the current date as material availability date irrespective of the sales order quantity.

All responses will be rewarded suitably.

Thanks and Regards,

Jejesh.

Available checking rule in SD.

It depends on the Availability group you have maintained in material master.

The checking rule specifies the scope of the availability check for the respective transactions in sales and distribution by specifying precisely which stocks, receipt and issue elements should be taken into account during the availability check.

Every checking rule is allocated to a checking group: together these two elements determine the final inspection requirements. In addition, the checking rule includes a specification whether or not an availability check should take into account the replenishment lead time ( i.e. Total time for the in-house production or for the external procurement of a product. In in-house production the replenishment lead time is determined to cover all BOM levels.)

Items for which the delivery date falls within the replenishment lead time, but for which there is no inventory, are confirmed for delivery after the replenishment lead time. In the case of items for which the delivery date falls after the end of the replenishment lead time, the system assumes that everything can be confirmed.

If you want the system to check the replenishment lead time, you should make sure that you have entered a value in at least one of the following three fields in the material master:

GR (goods receipt) processing time (Purchasing view)

Planned delivery time (MRP I view)

GR processing time (MRP II view)

Otherwise, the system confirms every requirement.

Ava checking group what you have maintained in material master and the checking rule for SD (in std system is A)

--combination of above will decide how the ava check to be carried out and decide the delivery date. This sitting is available in SPRO in OVZ9.

If you carry out the availability check using the replenishment lead time, you should plan ahead in regular intervals (on a daily basis for individual and daily requirements, on a weekly basis for weekly requirements) to prevent a shortage and therefore a possible delivery block. This shortage could occur if the delivery date of a sales order, which was confirmed the previous day for the replenishment lead time, is already within the replenishment period on the current day and therefore results in a shortage.

Hence,

1. Check the configurations for the checking groups which are contained in the standard SAP R/3 System.

2. Make sure that the checking group is maintained in the material master records. Depending on the plant, you can specify a checking group for each material type

3. Select the individual stock elements as well as the receipts and issues which should be taken into account during the availability check.

4. Select the field for replenishment lead time if you do NOT want to take the replenishment lead time into account.

Depending on above setting delivery date will e determined or delivery block in case no qty available can be designed.
